Overview
The 18293 was specified when the CS110 Electric Field Meter was ordered to have a CR1000M-4M Module installed in the CS110 before it left the factory. The 18293 was offered when the standard CR1000M had 2 Mbytes of data/program storage. In September 2007, the standard CR1000M started having 4 Mbytes of memory—making the CR1000-4M as well as the 18293 obsolete. Currently, the 18292 should be specified at time of CS110 purchase.
